Spatial information system based on spacevpx standard

Abstract

The present invention provides a space information system based on the SpaceVPX standard, comprising: an information plane, a system management module, a main control module, a switching module, and a functional module connected by mutual communication, wherein: the information plane is used for according to the internal modules of the system The data transmission rate between provides different data exchange topological networks; the system management module is used to provide the management strategy of each module in the system and the communication protocol between the modules; the main control module is used to limit and Each module is controlled to perform a corresponding task; the switching module is used to define the interaction relationship between each module; the function module is used to define the function that each module is responsible for. Therefore, a space information system for the SpaceVPX standard can be constructed, making the whole system more standardized and more applicable.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a space information system based on the SpaceVPX standard. Background technique [0002] The space information system is a space electronic platform integrating platform management, data storage, information processing and other functions. Improving the performance and reliability of the space information system and promoting the modularization of the space information system are current research hotspots. Among the currently known VPX information system platforms, the platform designs are ground applications based on OpenVPX, such as patents CN205389239U, CN105488566A, CN104243174A, etc; In the functional design of the whole machine. [0003] However, the above patents are all proposed based on the VITA65 (OpenVPX) or VITA46 standard, which lacks reliability design for aerospace applications, making the entire system not standardized enough and poor in applicability.
